assignors to United States Steel Corporation, a corporation of Delaware Filed Nov. 12, 1963, Ser. No. 322,957 6 Claims. (Cl. 72--161) This invention relates to apparatus for coiling wire and more particularly to coiling medium to high carbon galvanized steel wire No. 16 gauge or finer. Frequently the wire fails to wrap properly on the take-up due to its springiness and lack of uniformity in cast. This wild wire causes stoppage of the reeling and hence requires a stoppage or slowdown of the processing line. There is also a danger of the equipment being damaged or of injury to the workmen. The quality of the coils of the wire may also be decreased. While wire casters have been used, to the best of our knowledge, none of those in use will operate satisfactorily on medium and high carbon galvanized steel wire No. .16 gauge or finer.

It is therefore an object of our invention to provide apparatus for coiling wire in which a dead cast is provided in the wire being coiled.

This and other objects will be more apparent after referring to the following specification and attached dr-awings, in which:

FIGURE .1 is an assembly view of the apparatus of my invention;

FIGURE 2 is an enlarged view, partly in section, of the apparatus of FIGURE 1;

FIGURE 3 is a view, partly in section, taken at right angles to FIGURE 2;

FIGURE 4 is an enlarged view taken on the line IV-IV of FIGURE 2; and

FIGURE 5 is an enlarged view taken on the line VV of FIGURE 4.

Referring more particularly to the drawings, reference numeral 2 indicates a roller housing having a main leg 4 and a secondary leg 6 extending at right angles thereto. The housing 2 is located at the exit end of the wire processing line, not shown, such as a glavanizing line. Two large rollers or sheaves 8 and 10 are mounted on the main leg 4 with their axes parallel with each other and perpendicular to the leg 4. A smaller roller or sheave 12 is also mounted on the leg 4 with its axis parallel to the axes of rollers 8 and 10. The roller 12 is located between the roller 10 and a driven take-up block 14. Four rollers or sheaves 16, 18, 20 and 22 are mounted on the leg 6 between the rollers 8 and 10 with their axes parallel to one another, but perpendicular to the axes of rollers 8 and 10. The roller 8 is mounted on a shaft 24 which has a threaded portion 26, a square section 28 adjacent the head, a cylindrical collar 30, a cylindrical bearing portion 31 and a threaded portion 32. The leg 4 has a slot 34 therein which receives the square portion 28. A ball bearing 36 is mounted on the cylindrical portion 31 between the collar 30 which bears against the leg 4 and a washer 38. The roller 8 is mounted for rotation on the bearing 36. The roller assembly is held in place by means of nuts 40 and 42. A threaded opening 44 is provided in the leg 4 in alignment with the slot 34 and perpendicular to the axis of shaft 24. A cap screw 46 is threaded into the opening 44 and held in adjusted position by means of a nut 48. The roller 10 is mounted on a shaft 50 which is identical to the shaft 24. Since the mounting and arrangement of the roller 10 is the same as that of roller 8 it will not be described in detail. The position of the roller 10 is adjusted by means of a cap screw 52 and nut 54 in the same manner as roller 8. The roller 12 is mounted on a shaft 56 which, except for dimensions, is the same as shaft 24. Since the mounting of the roller 12 is the same as that of roller 8 it will not be described in detail. The position of the roller 12 is adjusted by means of a cap screw 57 and nut 58 in the same manner as rollers 8 and 10.

Four slots 60 are arranged in the leg 6, one for each of the rollers 16, 18, 20 and 22. Since the supports for the rollers 16, 18, 20 and 22 are all the same only one will be described in detail. The roller 16 is mounted on a shaft 62 having a threaded portion 64, a square portion 66 which is received in the slot 60, a collar 68, a cylindrical portion 70 and a threaded portion 72. A roller bearing 74 is mounted on the cylindrical portion 70 with one end bearing against the collar 68 and the other end against a washer 76 which is held in place by a nut 78 threaded on portion 72. The roller 16 is mounted on the roller bearing 74. A nut 80 threaded on portion 64 holds the parts in assembled relationship. A threaded hole 82 is provided in the housing 2 in alignment with the slot 60 and a cap screw 84 threaded therein and held in adjusted position by means of the nut 86.

In operation, wire W coming from the galvanizing line passes around roller 8 and is fed between rollers 16, 18, 20 and 22 as best shown in FIGURE 1. Wire W is then threaded around roller 10 and hence around roller 12 and the end attached to the take-up block 14 in the usual manner. The position of the rollers 8, 10, 16, 18, 20 and 22 is adjusted by means of cap screws 46, 52 and 84 to suit the particular wire being processed. It will be seen that the wire W contacts all of these rollers in such a manner as to urge their supporting shafts against the adjusting cap screws and since the wire is under tension the shafts will be contacting the cap screws during operation. The position of the roller 12 is adjusted according to the wire being processed to impart a cast in the wire such that it will wind uniformly around the rotating take-up lock 14 so as to provide a uniform coil of wire C. It will be seen that the roller 12 moves the wire W away from a line tangent to the take-up block 14 and roller 10.

While one embodiment of our invention has been shown and described it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.
